Sangamo Biosciences is putting a different spin on gene therapy. Rather than replace or supplement a mutated gene with an accurate copy, Sangamo researchers are introducing a mutant copy of the gene for the HIV co-receptor CCR5 into the T cells of HI
Telomeres are repetitive, noncoding sequences that cap the ends of linear chromosomes. They consist of hexameric nucleotide sequences (TTAGGG in humans) repeated hundreds to thousands of times. Telomeres protect the protein-coding sequences of DNA on
A transition-state mimic has the power to bind an enzyme at its tipping point as strongly as any available inhibitor and more strongly than most, preventing enzymatic activity. In order to replicate the structure of an enzyme’s transition state, whic
Vitamin D has a variety of actions in the body. It binds to the vitamin D receptor (VDR), which then binds to the retinoid X receptor (RXR) and activates the expression of numerous genes. Through this mechanism, vitamin D promotes calcium absorption
